  1. I don't seem to see anything that would indicate there is a brachiopod there.
  2. Thought some of you guys might appreciate this presentation about the mines that produced wulfenite in Arizona. He goes through quite a few mines across the state, and shows all sorts of specimen examples as well as some photos of the mines.
  3. Is it opaque, is it of metallic or glassy luster? Hard to tell in the photos. Does it seem heavy for it's size?
  4. Could be all sorts of things, calcite veins on limestone, quartz veins on a metamorphic rock, etc.
  5. Looks potentially sedimentary, not sure of much else.
  6. Lots of rocks are tough to identify by photo, minerals can be easier.
  7. Russia refurbed them during the cold war and then they were stored in cosmoline. It would take over $1000 to reproduce them today. Prices keep going up on them, just a few years ago you could get one for $89, last I checked in Cabelas they wanted $450, of course Cabelas always charges more. Ammo for them used to be 17 cents a round, but that is no longer the case.
  8. What he says is true, you will find much more at the pay place. However, going off to look on your own at least gives you a chance to find a rarer type of trilobite. At the pay place they keep the layers and beds that seem to have rarer specimens roped off from customers. I'm not sure if they actually confiscate specimens if someone were somehow able to finder a rarer species, but it's not likely they will find one anyway. There's one spot I need to revisit where I found the bottom half of a really large one. Unfortunately, I set it down for a moment and then was unable to find it again after looking everywhere at dusk. Still, it was evidence of larger/rarer trilobite species in the area. I tend to try to avoid the black shale myself. Prefer the Marjum Formation and Weeks Formation to the Wheeler Shale. Below is the first trilobite I ever found that I mentioned in some of our correspondence. It's a Modocia Typicalis in tan shale of the Marjum Formation. They aren't that concentrated in that area, but there are some there. Maybe a little more like nuggetshooting in a sense. At the pay place the value of the trilobites will normally run from approx. $5 to $20 vs. $80 to $300+ for rarer specimens.
  9. Cool stuff, nice pics. Very nice Asaphiscus Wheeleri trilobite there and neat topaz specimen. It's amazing that little cinder cone still turns up so much yellow labradorite. I went there once almost 20 years ago. I also stopped by Lake Sevier once to do a little photography and quickly found out that is was not entirely solid. I think during Spring and this time of year it would be at it's wettest. I was able to carefully go out on to the lake but it was rather muddy with damp salt. In contrast, the narrower salt flats out by Ibex Well are very dry. Great views of the Milky Way out there. Anyway, glad I was able to pass along a little knowledge of the area, glad you had some success out there. Let me know if you ever make it out there again and I'll try to join you on a Saturday (if you hit the trilobites then.) Fall is a good time, less snakes (at least in the trilobite areas) I've not seen snakes yet at Topaz Mtn, but that does not mean they don't exist there. Still, for the pay place (U-Dig Fossils) I get the impression that Fall is not a good time. I went there one Fall and the guy seemed to behave as if there was not much to find since they do their excavation blasts in the summer. He did not say that, I just inferred that from his body language and since I did not find as much as most people describe.
  10. BigRex, trilobites you have collected, last year.  Well the fossil bug has got me lately, and now wanting to get into some topaz too. I saw a post you made in Aug '17 or so last year about hunting up in UT amd the video you made on Youtube. I'd really like to come up that way and do some hunting for topaz and trilobites too. Any suggestions, tips, or even guiding other there? I don' have the 4x4 anymore, just 2 wheel, not sure that makes a difference. And what about the time of year? I'm interested in the next several weeks or so, maybe after the 7th of June. I know it'll be hot but I'm OK with that, I think. Let me know what you think or can offer in the way of finding success up there. I'm just shooting in the dark here, and other than Google Earth, not much in knowing the roads, area, claims, etc. Let me know what you think.

      Hi Jayray, feel free to shoot me an e-mail at biggrex@gmail.com. My inbox here is full. I typed something out, but preferred to not post it to my public profile. Thank you.

  11. I was raised in Central FL. Florida is pretty notorious for not having any rocks at all except maybe sand, clay, phosphate and some agatized corals and fossils preserved in swamps. That's pretty much it.
  12. Yes, some look like they might be petrified bone. I've not heard of petrified wood from FL but there are bones from time to time of animals from the Pleistocene, etc. I'm not saying it is impossible that it is wood maybe some might resemble palm wood too, but I would think bones is as likely if not more so.
  13. Looks like some type of rock covered by desert varnish. There is a good chance it is not the same color inside.
